Error when startingmetricbeat with v7.5.3

Elastic Stack Beats
5

Thanks. So the problem is that somehow there is a metricbeat-7.5.3 index, whereas Metricbeat is expecting this to be an alias.

At this point, I'd suggest the following steps:

  1. Stop all instances of Metricbeat 7.5.3.
  2. Delete the metricbeat-7.5.3 index as it doesn't have any documents in it:
    DELETE metricbeat-7.5.3
  3. Delete the Metricbeat 7.5.3 index template.
    DELETE _template/metricbeat-7.5.3
  4. Restart the stopped Metricbeat instances. This should recreate the template, the index alias, and the correct index.
